Reborn into the body of a silver-haired orphan in 1980s London, Reinhardt wakes up with memories that aren''''t his and a power that shouldn''''t exist. Deep within his soul lies the Holy Grail, a reality-warping relic that grants one wish a year—but with rules that even he cannot break. In a world where magic is a weapon and the timeline has already begun to diverge, Reinhardt isn''''t interested in being a hero. Armed with a Gacha System that rewards his greed, he begins a ruthless takeover of the Wizarding World’s economy. From bankrupting the Malfoy family to de-aging and reclaiming the powerful Black sisters, Reinhardt is rewriting the fate of magical Britain—one pull at a time. But as he summons legendary entities and builds a corporate empire that rivals the Ministry itself, a chilling question remains: In a game where the house always wins, what is the ultimate cost of his ascent?
